So to cut it short the movie mediocre ,, BUT ,, it does have some unpredictability and the events at the second half escalate really quick .. again it is not the perfect thrill/drama mix ,, but it had some unexpected ending "for me" ,, i mean the guy is or was :D a good guy but circumstances would bring the devil out of the angel.
The story is good,, even though the "chasing" looked long, the script was a bit short and direct ,, it had one unnecessary branch though , "the neighbor" i don't think that was related ,
The casting was very good,, the lead "Julián Villagrán" was amazing ,, his facial expressions were just perfection, and the girl "Ester Expósito" was also good ,. over-reacting and all.
Overall, the movie is not amazing piece of art ,, but it was good and it works fine in the thrill genre ,, and this is maybe only the 2nd Spanish movie i watch this year so i wouldn't say i'm disappointed.
